, Among thegprimary obJects of the invention are vthe provision ofa suspensionmeans which permits or accommodates, itself' to 4the rocking movements yof the booster ymotor which are incident to the normal running of the locomotive; the yprovision of a supporting or suspending mechanism which yieldmgly andwhich, therefore;constantly'urges the rn'otor` to its nornral operating position; and, in generah1 the provision of `aboostermotor suspensiondevice whichis' simple in con struction and application and which has suf,-v

The truck bolster 6 is pivoted to the frame-of the tender by means of a pin 7 in accordance with usualfor common truck structure. The booster motor 8 understood that the apparatusof the present invention may be applied to any suitable type of pivoting vor swivelingtrilclr and alsolthlat r fextends outwardly therefrom over the fJo'ost-V.k

VThe overlyingy supporting structure isclaimedYV lherein only in combination withv certainfof the parts to be described hereinafter. v

Thelink 18 depends-rom the arm 11 and extends through an aperture19 in the booster bed `plate 20. The underside of' the bed plate adjacent to the'aperture 19is providedwith a-concaved 'surface indicated 21 which iis, f

adapted to seatlon the upper'conveX surface' 22 of the bearing block 23, the llatter 'being se'cured'toV the lower v end of thelink lg-byl means 'of avr suitablekey or pin '24. i The bed platez'QO is further provided' with an annular shouldervatj'the upper edge of the' aperture 19, the said shoulderbeing adapted to 'engage the downwardly projecting circular portion 25v'of the Vmember 126, Thegmember 26 in turn is provided with" a rounded or convexv surface ,Q7-on its upper` side whichcooperates with a complementary concaved surface'Av on' the lower' :ide Vofthe collaror ring'QS. At'

aV point somewhat above the ring'28 the link 18 is providedfwith aange 29- between which spring is arranged.

and the upper surfaceof the member 28 a coil The operation ofthe device should be appai'ent, but it might be noted that the cooperating concaved andzconvex surfaces above and below the booster bed plate together with the spring 30 permit the maximum possible vfreedom of relative movement of the parts," particularly 'with respect to the Afrequent rocking movements which are normally set up when the vehicle passes over unevennesses or irregularities in the trackway. i The `device also operates to yieldingly retainA the booster motor in its' normal operative position and is particularly advantageous in overcoming any tendency of Athe' boosterfinotor to move orv .jerk upwardly during operation.

vMy invention therefore provi'desaflinksus-y pension de vice whichaffords the'greaftest possiblefreedom` of movement and at the `same* time aifordsadequate support for the booster motor and operates to yieldingly.` retain the booster motorin its normal operative position.
